other rotor to provide pockets for the jet or jets of fluid under pressure.

The principal objects of my invention are to provide turbines, each embodying two rotors which may be the product of the same mold or in other words, complemental, thus reducing the cost of manufacture, and facilitating assembling and replacing of a broken or worn rotor; to provide turbines each embodying two rotors, and each rotor embodying a peripheral flange to extend laterally of the recesses of its coacting rotor and closing the said recesses laterally prior to and during the entry of the jet into the pockets thus formed by coacting recesses,

'but which render the said recesses open laterally after the impact of the jet against its walls, thus relieving back pressure by freely giving up the fluid from the turbine rotors after it has served its purpose as an impelling means.

Other objects of my invention will appear in the following detailed description, taken in connection with the accompanying drawings, forming a part of this specification, and in which drawings:

Figure 1 is a view partly in elevation and partly in central vertical section through a turbine constructed according to my invention.

Fig. 2 is a central horizontal sectional view through the same.

Fig. 3 is a central vertical transverse sectional-view through fluid-conducting and controlling means, showing parts of the turbine in operative relation thereto, in side elevation. i

Fig. 4 is a fragmentary perspective view of one of the rotors.

Fig. 5 is a perspective view of a casing forming means. v

In the drawings, where similar characters refer to similar parts throughout the several a' part of the fluid-conducting.

views, A designates a casing provided with an ingress opening B and an egress opening C for the fluid; D rotors in said casing, carried by shafts E and F; G fluid-conducting means; and, H fluid-controlling means.

Referring first to the rotors D, arranged within the casing A so as to peripherally confront one another, they are formed to i provide a plurality of peripheral recesses 6, each rotor being closing said recesses laterally, said flange extending beyond said recesses a distance greater than the depth of the pockets, for a purpose to be subsequently set forth. The

recesses 6 are open laterally of the rotor at its face opposite to flange 7 and may be provided with a circumferential groove 9 at said face, as clearly shown in Fig. 4 of the drawings.

The recesses 6 may be of any shape, but it is preferred to form them with a relatively flat radially disposed wall and an arcuate wall 12 leading outwardly from the base of wall 10 to a point adjacent the outer end of the next adjacent wall 10, as is clearly shown in Fig. 1 of the drawings.

The rotors are so arranged on their respective shafts E and F, supported by bearings 13 that the flange 7 of one rotor extends laterally of the adjacent recess 6 of the other rotor closing the same as the said recesses approach one another for the provision of apocket as is obvious from an inspection of Fig. 2 of the drawing. These flanges may extend, if desired, into the said grooves 9 so as to seal the recesses 6 as the coacting recesses aline at the plane common to the axes of rotation of the rotors D.

Referring now to the fluid conducting means, in the example shown, it may comprise a pipe or conduit'lc; a casing 15 extending through the ingress opening B of casing A; nozzles 16 at that portion of casprovided with a flange 7 1 extending laterally at one face of the rotor,

ing 15 within the casing A, and directed toward the coacting recesses 6; valve-controlled drain pipe 17 and a conduit 18, the

The means H, in the example shown, comprises three sets of meehanisms,-an automatic speed control 24, a manually-operated control valve 25; and mechanism 26 for moving the casing toward or from the rotors D. Referring first to the mechanism 24, it may comprise a governor 27 operated'from shaft F, and through comeshing bevelgears 28 and 29, the latter of which is rigid with an upright shaft 30 on which governor 27 is mounted; and, a valve 31 adapted to be moved toward or from a seat 32 in casing arranged in connection with the drain pipe 15, as by having valve stem 33 operatively connected with a lever' 34 actuated by governor 27 as through collar 35, the lever 34 being pivoted as-at 36. Thus, as the turbine speeds up the governor 27 is actuated, imparting movement to lever 34 and reciproeating valve 31 according to the speed.

The valve 25 may be of any suitable type,

.disposed in. casing 15 and adapted to be 17 illl such a manner as to be oscillatable with respect thereto, and by rotating the bolts 39, the abutments 40 and 41 may be moved away from one another, or toward one another, actuating the casing 15 accordingly.

The casing 15 may be provided with arcuate grooves 42 within the casing A, said grooves to accommodate the flanges 7 and for the purpose of providing fluid-tight engagement of portions of the turbine to prerent the escape of fluid, under pressure,

about the casing 15, The said casing is also formed with arcuate walls 43 adjacent the rotors, and unions 44 may be provided in the conduits 14 and 18 to facilitate detachment of the'casing 15 from operative relation to the turbine for the purpose of repairer to enable said casing to be cleaned.

The operation of the turbine is as follows: Assuming that fluid, under pressure, is introduced into the casing A, through nozzle 16, the said fluid impinges upon the walls of recesses 6, of rotors D as they are approaching the plane common to the axes of rotation of said rotors, and as the said recesses are approaching one another to form pockets, at which time the flanges 7 cooperate with the recesses of adjacent rotors to seal the said recesses 6 laterally. As the recesses 6 pass the said plane they are moved away one from another permitting the fluid to escape from operative relation to the rotors. It is to be observed that the fluid may escape not only from the peripheral nae-2,51 1

portion of the rotors but may find egress laterallyof each rotor at the face thereof, opposite to flange 7.

-The rotors B. may be the product of the same mold inasmuch as they are complemental, and when disposed with their peripheries confronting one another, and with the flangeof one rotor fitting into the groove 9 of the other rotor or to lie laterally of the adjacent recesses 6, a plurality of substantially air-tight pockets are formed intermediate the rotors and against the walls of which the impelling fluid impinges.

Changes in details may be made without departing from the spirit or scope of my invention; but,
